` ROTARY POWER-WASHER.

'.l'o all whom it 1mi/y` concern:

Be 'it known that we, THOMAS F. LiNEGAR and HENRY M. S'ronMs, citizens of the United States, residing at Seattle in. the county of King and State of l ashington, `have invented certainnew and useful Improvements in Rotary Power-Washers, ofV which` the following` is a specification.

The object 'of this invention is lto provide a new' and im i'oved scrubbing apparatus which is especia ly designed for use 1n cleaning automobiles, and other'vehicles, though .it vmay advantageously be employed for analogous operations in other Work.

The invention, generally stated, may be said to consist of a brush mounted for rotation in acasing which is arranged to be attached by a fiexible hose with a source ot water supply which affords 'power for opl Fig. 3 is a plan View. Fig. 4 is a side elevation of the runner removed from the casing and illustrated with a modified form of brush.

The apparatus vis provided with a rotary brush having an annular shaped body 5 which is mounted upon diskwebs 6 which are respectively inserted within the ends of.

said body so as to afford a recess 7 at each end of the latter. Formed centrally of each of said webs and projecting from the side `ilface is a boss 8 and extending radially therefrom is a series of longitudinally curved vanes or blades 9 which overlie the' respective sides of the body and terminate in proximityto the periphery of the same. The disk members 6 are removably fitted within the brush-body andare rotatably engaged therewith by the provision of lugs 10 and 11 upon the disks and brush-body, respectively.

A suitable containing casing is provided for the brush and lmay be composed of a semicircular central portion, 12 which is chambered to accommodate the brush and is offset at the sides to provide correspondingly shaped wing compartments 13 for containing VApplication Mede-April 2, 1909. Serial-No. 487,407.

axle 22 extendin 4, 'which may belformed o the runner vanes 9. The side walls 14 of' said wing compartments are desirably iliade of a substantially circular conguration with a diameter approximately that of the vanes toafl'ord shroud plates for preventing the water being scattered.

lrotrudi-ng from the peripheral wall of the casing and diametrically opposite to the aforesaid opening is a tubular extension 15 which is screw-threaded to receive the coupling 1G of a flexible hose 17 for making connection with a source of water supply.

AWithin the casing said extension communicates by a transversely arranged conduit 18 with two converging assa e ways V19, Fig. 2, which are dispose to lrect ithe owcr mediunito impinge the vanes principally within the respective recesses for rotating the brush. Communication is also had by relatively small holes 20 between tliecondint 18 and the interior of the brush-chamber to furnish a supply of water, directly to the brush to facilitate the scrubbing operations.

Extending from the spaces between the vanes and through the botly to the outer perimeter of the same is a series of holes 21, Fig.y 2, for affording means for the escape of such water as may be entrained within the recess compartments to be delivered to the brush propenand acting supplementary to the offices of the holes 20.

The brush is mounted, for rotation on an through the web bosses 8 and is supporte at its ends by the casing walls 14. The brush may be of any type suitable to the work which is to be done as, for example, bristle-brushes, such as indicated by 28 in Figs. 1 to 3, inclusive, are

well adapted to scrubbing vehicles; while for other services the brush may be provided with a noduled peri hery 24, see Fig.

l) rubber. The o ration of the invention is as folen water under pressureis ad mitted into the casing from the hose 17 it will be-caused to flow through the conduit 1S into the passages 19 whereby it is directed to strike the varies 9 to effect the rotation Y of the brush. If the brush when thus actuated is brought into contact with the surface of an object'to be scrubbed it is evident that it will-performv such action most elliciently.; This scrubbing action is more ef1 fectively accomplished with a supply of water delivered through the holes 20 leading from the conduit 18 and also through the may be directed from said vaiies to the brissaid base,

.binatiom a partially inclosed casing, having a transverse chambered base, a brush having y holes 2l. The apparatus as a whole is l manipulated in the hands of an o rator when grasping the casing extension 15, which may be extended any convenient distance vfor this purpose, and is operative when held at `any inclination asbest suited to the work; l

Having described our invention, whatwe claim, is- I 1. A rotary Washer, comprising, combination, a partially inclosed casing having a transverse chambered base, a brush having a cylindrical body andadapted to rotate in s aid casing, ends in said cylindrical bod having outwardly projecting bosses, a sha t extending through said bosses and into the sides of said casing, and radial curved vanes extending from said bosses on the outer face of each of said ends, said base having conduits at each end whereby water may be directed against said. vanes and the body of said brush having conduits whereby water tles of said cylindrical brush.

2. A rotary washer, comprising, in combination, a partially inclosed casing having a transverse chambered base, a brush having a cylindrical body and adapted to rotate in said casing with its bristles adjacent said chambered base and radial varies carried by said body and extendin a partially within said cylindrical body, said chambered-base having conduits at its ends for'directing wa ter against said vanes, and conduits for supplyin waterto said brush, and said cylindrica' body of thebrush having conduits for supplying `the water directly from said vanes to the outer side of said cylindrical body. l

3. A' rotary washer, comprising,'in coma cylindrical body and adapted to rotate in end members inserted in the ends comprising an annular bod land rotatably mounted on said shaft, operating means carried by said bodyyand said end members to prevent relative rotaof said cylindrical body to provide an overhanging margin of the latter on each,end and vanes extending from each of said end. members `and underlying Said margin, said chambered base being formed to conduct w'ater to said vanes and said overhanging margins being formed to direct water to the outer periphery of said body.

. 4. A rotary washerz comprising, in combination, a casing having a chambered base, a 'shaft mounted in said casin a brush rotatably mounted on said sha said'brush comprising an annular body, a plurality of lugs formed on the interior of said body,

end members mounted on said shaft and slidably mount-ed on said annular body, the inward movement of` said end members ing prevented by said lugs, lugs formed on bey said end members to engage said lugs in said.

body to prevent relative rotary movementv of the end members and the body, vanes on said end members extending therefrom to the sides of the casing, and means to conduct water from said chambered base to said vanes.

5. A rotary washer, comprising, in combination, a casing having a chambered base, a shaft mountedin said casin a brush rotatably mounted on said sha said brush end members inserted into -the ends of said annular body tion thereof, vanes carried by said end inembers and extending therefrom to the sides of the casing, and means to conduct water from the chambered base to said'vanes.
